To all whom it may concern: I

Be it known that I, J 011m lV. Lninnirr, of Anderson, county of Madison, and dtate of Indiana, have invented a certain new and useful Power-Transmission Mechanism; and I do hereby deelare.that the following is a full, clear, and exact description thereof, reference being bad to the accompanying d awings.

The object of this invention is to provide an improved power transmission mechanism adapted particularly for friction driven auwith any other mechanism where either the must be capable of some longitudinal movement v The nature of the invention will be understood from the accompanying drawings and the following description and claim.

In the drawings Figure 1 is a plan view of said aechanism, the driving and driven shafts being partially broken away. Fig. 2 is an elevation of the cou iling from the line 2-2 of Fig. l, the driven shaitt being in section. on said line. Fig. 3 is a horizontal loin Fig. 1. Fig. -l-

a vertical longitudinal central section on the line 'l '-lof Fig. 2 and showing the changml position of the driven member.

There is shown herein a driving shaft 10 and a driven shaft. 11 with a driving member l2 secured to the driving shaft and a d rivcn member 13 secured to the driven shalt. "hilc shafts are shown, said. driving and driven members l)v and 13 may lic secured to any other driving or drivcn mcans: For instance, t'hc driving mcmhcr Ii can hc scenrcd to the ll v whccl dircctl instead of to the engine shaft '10 and aisd, the driving and driven. members 12 and 13 can be -intcr changed. the member 13 being secured to the driving shaft 10 or other driving means, and the driving member 12 being secured to the driven shaft 11, for this invention lates only to the form and relative arrazr ment of the men'il'i'ers 19, and of What they may be seen The coupling member 1 cylinder of even internal. by the boltsvl l to the l'll driving shaft 10 by a l.

cylinder 12 a pair of oppositely extending substantially radial arms 1,7 extend, as shown in Fi 1 and 4-. They entend at. an inclination so that their outer ends are in a plane nearer the open end of the cylinder than the closed end thereof.

The member 13 is clamped on the end of the driven shaft, 11 by bolts Qt) through cars 21 on a split sleeve Said member 13 has a cylindrical portion which fits snugly in the cylindrical portion of themelnber 1i sons to be longitudinally slidable therein. and one serves to guide the other in the longitudinal movement of either. Said mom;- ber 13 has a pair of oppositely extending: arms 2% corresponding with the-arms 17 on the other member 12. I

In assembling the'two members, the two sets of arms are placed ninety degrees] apart, as shown in Figs. 1 and 2, and their ends are connected to flat spring plates or strips 1 25 by rivets 26, or the like. The spring strips- 25 yield in a direction longiti'i ftinallj of the shafts but in no other-direction, and, therefore, they permit longitudinal nio vement of either n'iember or flexible movement, oi the coupling. 80

In friction driven automobiles it is desired .1 that the driven shatts he longitmlinall l l movable by the pedal mechanism of the ma: chine so as to move the frictioi'i disks i'ntc. i and 'out of engagement with each other and ads '0 control the frictional engagen'rent oil the .sks when in operation, for when blimb-f 3 ing a hill or doing heavy work, the frittt-ioilal, engagement must be greater than is aiccc." sary at othcr thncs. Since this strain ltf ccnr-blt'l'nblc and thc t rsional strain is greatl 2 HI large antonmhilrs, the constructionfot the coupling herein shown becomes \"lRVlllllJ Mfi tant as the members etl'ectnally guide each! other and hold each other in place, in ad-li-l tion to the gu an; and holding arising trom the arms ll" and 22stand siring plates or strips 25. y i

I claim as my invention:
